I I p As the dischargeoutlet 21. approaches a dischargingposition the projection 25 on the respective outlet will engage a stopor member 29 arranged inthe path of the projection the slid able type t45 Y by-anelectro-responsive device 48, preferably and which stopoperates to shift the clo- I sure 23 against the stress oi the spring 26to uncover the outlet 21.

Any suitable means may a' suitable and eflicient means embodies asprocket wheel 30 to which is connected one end 015a link 31, the otherend of the link being connected as at 32 with the receptacle so thatwhen the sprocket wheel 30 is rotated 7 in the directionindicatedibythef arrow-in Figure 1', the receptacle 11 will be rockedknown construction,

first into the position shown in Figure 1 and I I later into theposition shown injFigure 4.

.- The sprocket wheel is adapted to bedriven from a motor '33 throughthe medium of a speed reducer 34 of any {suitable or. well and the shaft35 of which speed reducer is connectedby means of a belt 36with theshaft 37 of the motor.

. Connected with thelshaft 35 of the speed reducer is a pulley, overwhich another end less belt 38 passes, and this belt'in turn passes overa pulley 39 rotatably mounted upon the supporting" structure 10.-Secured to the the .operation'ot themot'or 33. r

Loosely mounted upon the shaft40 is a sprocket wheel/42 over which asprocket chain 143 passesand which sprocket chain also passes over thesprocket wheel '30.

f Connected to; rotate withthe sprocket wheel 42 is a disc44 andpivotally mounted upon the disc intermediate its ends as at 45 is alocking dog 46 provided with: a spring 47 hat tends normally to move thedog 46, into engagement withfthe locking member 41 to lock the disc 44'andthe sprocket Wheel42 thereby with the shaft40' for rotation therewithand in the form of a solenoid, the armature 49 of which is operativelyconnected with one endof alever 50, the latter beingop'ivotally.supported intermediate its ends as at 51. One end of the lever 50 isadapted to be moved into the. path of rotation of a portion of the Y46and aspring 52 tends normally to move'the lever 50 into such position sothat when the disc.,44 islocked for rotation with he shaft40, and thedog '46Yis-bodily rotating withthe disc, one end of the dog will contactwith the end of the lever 50 which is arranged infthe path of movementthereof to trip the dog againstthe stress of the spring 47 and therebyunlock the disc 44 ,with're spect' to the shaft 40 to arrest therotation of the sprocket wheel 30: A retaining pawl 53 may beprovidedfwhich co-operates with a shoulder- 54 on'thedisc44-fo'r lockingthe disc be provided 'for rocking the receptaclell about its pivot, but

tion the material to be to the impart a rotationwto the sprocket wheel30fromthe motor. T V j 'The operation of thedog 46'is controlled broughtinto rated contacts 64- 44 against retrograde movement whenthe dog 46 1smoved into an lnoperative or unlocking position with respect to themember 41, a spring 55 being provided to retaining pawl 53. I

The receptacle 11 will thus be rocked about itspivot to alternatelydischargethecontents thereof into thecans or containers control the "28,p which latter are mounted upon a suitable support 56 and the rocking ofthe receptacle 11 is automatically controlled by the delivery ofrespective chambers 18.

In the present application'of the invendispensed is disclosed the liquidor material to be dispensed into the o as aliquid which, when the partsarein the position showninFigureB, will fill one off the chambers '19by-being discharged through the space between the transverse partition14 and the end of the respective inclined partitio'n' 15-,a vent pipe 57beingfprovided for each of the chambers 19.

Assoon as one ofthe chambersilfil is filled with the liquid, anyadditionalamount delivered into the receptacle 11 will flow over thepartition 14 and intoone ofthe receiving chambers 18 toaccumulatetherein andthe accumulation of the liquid will operate orraise a float 58 connected with a. rod 59 that moves in suitable guides60. One of these floats and an electric circuit make and break device,hereinafter to be described, isasso: ciated with eachof the chambers 18andthe respectivefloatswill rise and fall according" quantity of liquidin the chambers 18."

These float devices, operate to control the electro-responsive device 48through the medium of contacts 61- 62. To the contact 61 is connected aconductor 63'Lwhich is also connected to'a contacti6i4. Acontact 65 isspaced from the contact 64 and co-operates therewithin a manner to bedescribed, and

connected with this contact 65- is a conductor ,66 which: leads from oneside of a suitable source of-supply,- such as-a battery 67. 7 Leadingfrom the other side ofthe battery is a conductor 68 which is connectedto one end of the winding ofthe electro-responsive device 48. v I 1Connected to the other end of the winding of the electro-responsivedevice is a conductor 69 which is also connected with a contact 70, thelatter being disposed in a position that when the float 58 rises thecontact62'will be engagement with the contact70, thereby completingthecircuit through the electro-responsive device 48 and the sepa manner. I

Connected for rotation with the vpulley '39 is a disc 71 formed'ofanysuitable insulating material such as fiberor the like and carried in thefollowing by the disc is a contact 72 which passes through the disc andis exposed; onboth sides thereof. This disc 7i operates between access;

machine will be clearly understood from the foregoing description, butbriefly stated it is as follows a Assuming the parts'to be in theposition- -20 shown in Figures 1 and 3, and liquid is being suppliedthrough the pipe 20,the liquid will accumulate in the compartment 19which is elevated until the compartment 19 is filled, as shown in Figure3.1.

During the filling of thiscompartme'nt the: liquid will be dischargedfrom the compart ment 19 which is lowered and any surplus amount ofliquid will flow over the partition 14 into the other chamber 18. As theliquid flows out of the chamber 18 which is elevated and into thechamber 19 as shown in Figure 3, the float 58 in that chamber will belowered, thereby moving the contact 62 away from the contact 7 O tobreak the circuit through the electro-responsive device 4 8. This willrender the electro-responsive device inactive so that the spring 52 willposition the end of the lever 50 in the path of movement of a portion ofthe dog 46 to cause the discs 4 1 and 71 to be locked for rotation withthe shaft 40 to shift the receptacle 11 from the position shown inFigure 1 to the position shown in Figure 4. V I

As soon. as the other or filled chamber 18 is raised, the float 58 willbe held raised until the liquid flows from the chamber 18 intothechamber 19 sufliciently' to cause the float to drop to move thecontact 62 away from the contact 70. 4 It has been found that inoperation, a considerable amount of electricity will be consumed in adays operation of the device if the circuit to the electro-responsivedevice is not promptly broken after the receptacle is shifted, and ithas also been found'that the contact 62 will not always promptly moveout of engagement with the contact 70. Therefore, in order to conservethe amount of electricity employed and to insure a prompt breaking ofthe circuit through the electroresponsive device 48 the additional makeand break device 64,-65-72 is provided.

The circuit for the other chambers 18 and 19 and float 58 is the same asfor the float device just described.

In order to remove the receptacles 28 after i While the preferred formof they have been-filled, a suitable conveyor 73 maybe provided.
